Example one

As shown in fig. 1-7, the present embodiment provides a waterproof assembly, which includes a side shell 1 and a grid plate 2, which are stacked, wherein the side shell 1 is provided with a plurality of first ribs 3, first channels 4 are formed between adjacent first ribs 3, the grid plate 2 is provided with a plurality of second ribs 5, second channels 6 are formed between adjacent second ribs 5, and the first ribs 3 and the second ribs 5 are arranged in parallel at intervals. The first ribs 3 are arranged opposite to the second channel 6, and a space is formed between the first ribs 3 and the second ribs 5 in the through direction of the first channel 4, however, in the above arrangement, the second ribs 5 are also arranged opposite to the first channel 4.

In the above embodiment, because the form of staggered layout is formed between first rib 3 and second rib 5, first rib 3 is just to second passageway 6 setting, and when external liquid splashed the outside of side shell, partly can be blockked by first rib 3 directly, and partly can enter into first passageway 4 between first rib 3, and the liquid that gets into in first passageway 4 then can be blockked by second rib 5 on the grid plate 2 to can realize certain waterproof effect. In addition, as the first ribs 3 and the second ribs 5 form intervals in the penetrating direction of the first channel 4, the first channel 4 and the second channel 6 can be kept in a communicated state, and the two sides of the waterproof assembly can still keep the circulation and exchange of air flow through the first channel 4 and the second channel 6.

In the above embodiment, since the first channel 4 has a certain width, when the spraying direction of the external liquid is completely along the penetrating direction of the first channel 4, the liquid entering into the first channel 4 can be just blocked by the second ribs 5, but when the spraying direction of the external liquid is shifted left and right with respect to the penetrating direction of the first channel 4, there is a possibility that a part of the liquid is directly obliquely injected into the second channel 6 through the first channel 4, and the waterproof effect may be reduced. Based on this, as shown in fig. 2 to 5, the grid plate 2 further includes third ribs 7, the second ribs 5 are formed with the third ribs 7 on a side surface facing the side shell 1, and free ends of the third ribs 7 extend into the first channels 4, so that the third ribs 7 and the first ribs 3 are sequentially and alternately arranged, which can be described as first ribs 3 extending into gaps between the third ribs 7, and the first ribs 3 and the third ribs 7 are spaced from each other in the width direction of the first channels 4. Through setting up third rib 7 between adjacent first rib 3, can block some slant splash's liquid, can realize getting into the interior liquid of first passageway 4 to each angle and block through the width dimension of adjustment third rib 7 for first passageway 4 and the distance that third rib 7 stretches into in first passageway 4.
